Disassembly and Rebuild Procedure

Every ABEX 4467 gets a controlled teardown on our bench. We document condition, replace what’s needed, and reassemble to proper operating condition.

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.
  • Final Performance Verification: After reassembly, each valve undergoes bench-testing against published performance specs.

Hydraulic Testing Process

With over a dozen dedicated flow test stands and a Hagenbush proportional valve system, we verify flow curves, hysteresis, frequency response, and more. Performance reports and graphs are available for purchase on request. Our pre-shipment testing verifies proper functionality.

Repair, Rebuild and Exchange Options

Beyond standard refurbishment, we offer specialized overhauls for your ABEX 4467 unit. Our teardown process includes leak testing and internal inspection, using only replacement replacement components.

Maintenance Tips

  • Store spare ABEX 4467 valves in a clean, dry environment to prevent corrosion and contamination.
  • Check valve alignment carefully to prevent undue stress on internal components.
  • Replace inline filters according to maintenance schedules to maintain proper flow rates.
